The russet antshrike (Thamnistes anabatinus) is a passerine bird in the antbird family. It is the only member of the genus Thamnistes. It is a resident breeder in the tropical New World from southern Mexico to northern Bolivia. It is a bird of forest, old second growth, semi-open woodland and edges up to 1,500 m (4,900 ft) altitude. The female lays two brown-speckled white eggs in a deep cup nest 7–15 m (23–49 ft) high in a tree, usually in a semi-open location. Nest-building, incubation, and care of the young are shared by both sexes.
